different Work Schedules

FTP to a week old baby. After our 6 weeks is up both daddy and I must go back to work... His work schedule is FRI-MON 6pm-430am (graveyard) and mine is MON-Fri from 745am-300pm(day shift). As our baby gets older I'm wondering where we'll find time to rest for work?? Parents with different schedules how'd you guys cope? What are some techniques that worked for you? And what was the hardest part of having different schedules?
